The public charging stations are 30 amp because that is what the standard was. There was a company that you may have heard of that petitioned the SAE to adopt up to 80 amps.
In the mean time, this company used a 70 amp charge station for their car with a proprietary plug.
Yes, you are being funny, but someone who doesn't understand the details might be confused. There is really a higher power j1772 standard, with the same standard j1772 plug that works on all cars. Cars that have lower capacity chargers (every car except teslas, like leafs, volts, fords ev, etc) can still charge at their maximal rate even if they aren't using all the capacity of the higher power chargers. It used to be that tesla roadsters could not handle > 80 amp chargers, but that problem was finally fixed. Teslas can also use this standard as every model s comes with a converter to j1772 and tesla roadsters have an adapter that most of those owners purchased.
This public charging station should probably use an 80 amp charger. I'm just putting this out there in case say someone from the city council in that town is reading this thread, I wouldn't want them to be confused.
You don't really think they should use a 30 amp j1772 there, do you? There is every reason to use a high power j1772 there.
